docs: close built-in event plugin todos

Problem: Todo 47 and its safety/compatibility follow-ups remained open after all four plugins passed bounded specification and quality gates.

Risk: adapters remain lab-only mocks; production session/device/calendar/search integration and runtime-scoped deduplication remain separate work.

 # Todo 47 Built-in Event Plugins Plan
 
-**Status:** in_progress
+**Status:** done
+
+## Result
+
+Added four flat namespaced built-in plugins with injectable session, device, calendar, and search ports plus deterministic in-memory adapters. The default registry preserves the original lab tools and exposes the new definitions to both invocation modes. Final full verification: `313 passed`, one existing warning.

 # Todo 47.1 Plugin Normalization and Validation Plan
 
-**Status:** in_progress
+**Status:** done
+
+## Result
+
+Added generic deterministic normalizers shared by text and provider sources, standard/custom format checking, strict blank/invalid input rejection, safe volume parsing, and canonical adapter cache keys while preserving provider raw arguments and no-fallback behavior.

+Closed negation and malformed numeric side-effect gaps, canonicalized integral floats, preserved fallback provenance, restored standard RFC3339 behavior, and kept positional definition constructors compatible.

 # Todo 47.3 Bare Volume Numeric Guard Plan
 
-**Status:** in_progress

+## Result

+Mirrored malformed-number protection across the existing bare `volume to`, `volume at`, and `volume=` syntax; final bounded quality gate approved.
